490 , BOTANY OF GREAT YARMOUTH. [April, 



lity be determined, in others it cannot be ascertained by the 

 closest scrutiny. The sweet scent of the Eglantine, or Sweet 

 Briar, evidently proceeds from the numerous minute glands with 

 which it is invested. This may be proved by inspection with a 

 pocket lens of even moderate power. The same holds true in the 

 case of several others of the Rose family. Some plants contain 

 an aromatic oil, as Origanum. The Hyperica have their leaves in 

 most cases perforated or pitted by transparent dots, which become 

 visible to the unassisted eye when held up against the light. 

 Hypeincum pulchrum in a great degree possesses a strange odour, 

 quite different from anything with which I am acqiiainted. The 

 peculiar perfume of this genus undoubtedly proceeds from the 

 numerous punctures on the leaves, which appear to be pellucid 

 cells containing an odoriferous, volatile essential oil. The fra- 

 grance of the Aurantiacea is evidently traceable to a similar 

 source ; indeed, the Hypericacece and Aurantiacece claim a close 

 affinity in numerous points of structure. It is unnecessary for 

 me further to trespass on the reader's time and patience ; what I 

 have endeavoured to unfold will, I trust, at an early period be far 

 better treated and elucidated by others whose extensive know- 

 ledge and qualifications greatly surpass my own.

REMARKS ON THE BOTANY OE GREAT YARMOUTH. 

 [From a Correspondent.) 



The plants of this part of the county of Norfolk were probably 

 better known during the latter part of the eighteenth century 

 and the earlier portion of the nineteenth, than they are in our 

 own days. The late Mr. Dawson Turner, of Great Yarmouth, 

 the author of the ' Botanist's Guide,' and Mr. Wigg, both his 

 contemporary and predecessor (?) in this field of research, also 

 Mr. Dillwyn, of Swansea, made the botany of this district emi- 

 nent. 



Since that period, some changes have imperceptibly taken 

 place ; for example, the Denes have been enlarged, drainage and 

 cultivation have introduced some new plants, while other species 

 have disappeared. It is now nearly sixty years since the publica- 

 tion of the ' Botanist's Guide,' and upwards of twenty since the
